What was dry farming and what was some of the new machinery that made it possible?

The correct answer is C.

Religion played a huge role in Middle Age and Christianity was the most common and practiced one. Many Christians, including members of the clergy, held the opinion that the Jews were responsible for killing Jesus. This led to medieval antisemitism.

As a result of this, the Jews were stigmatized and punished. Many professions were closed to them and they were considered socially inferior. They dealt mostly with money lending, tax and rent collecting. Lending money for interest was considered a sin in the Christian religion and forbidden to Christians.

Due to their forced occupation, the Jews became unjustly known as greedy and insolent. This stereotype is still commonly used today.

During the Black Death epidemic in Europe in the 14th century, the Jews were made scapegoats. They were accused of causing the disease by deliberately poisoning the water wells.
